Application filed September 16, 1907. Serial No. 393,097.

To all whom it may concern:

Be it known that we, SAMUEL RICHARD and FRED GLUGK, citizens of the United States of America, residing at East Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented certain new and, useful Improvements in Advertising Devices, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to advertising devices, of that type designed for displaying business cards, announcement cards, and similar notices in hotels and public places. The device may be even constructed upon a very large scale for displaying sign boards upon public thoroughfares.

Our invention aims to provide a novel device for intermittently displaying signs, the devicebeing electrically operated and the illumination of the signs automatically controlled.

We further aim to provide a device which will be positive in its action, free from all danger of injury by ordinary use, thoroughly protected from the forces of nature when used as an outside advertising medium, and last but not least, a structure that is simple and durable and easily accessible.

The invention will be presently described in detail and then specifically pointed out in the appended claims, and reference will now be had to the drawings wherein,

Figure 1 is a longitudinal sectional view of our device, illustrating the mechanism thereof in front elevation and with the circuitmaking and breaking mechanism not shown, Fig. 2 is a cross sectional view of the device taken on the line w w of Fig. 1, looking in the direction of the arrow adjacent to said line, Fig. 3 is horizontal sectional view of the device, partly in plan, also illustrating diagrammatically the electrical circuit of the motor used in connection with the device, Fig. 4 is a cross sectional view of the device, taken on the line a vc of Fig. 1

, looking in the direction of the arrow associated with said line, illustrating diagrammatically the electrical circuit and source of energy employed for illuminating the exposed signs of the device, Fig. 5 is a similar view" taken on the line y-y of Fig. 1 looking in the direction of the arrow contiguous to said line,l ig. 6 is a front elevation of the device, partly broken away, Fig. 7 is a side elevation of the ratchet mechanism forming part of the device, Fig. 8 is a similar view of a portion of the ratchet mechanism, Fig. 9 is a rear elevation of the ratchet mechanism, Fig. 10 is a similar view of a portion of the same, Fig. 11 is a similar view of the trip constituting part of the ratchet mechanism, Fig. is a front elevation of the ratchet mechanism and trip, and Fig. 13 is an elevation of. a portion of the ratchet operated shaft.

To put our invention into practice, we construct the device of two end plates 1 and 2, these plates having their lower ends flanged, as at 3, whereby they can be secured upon a suitable base plate or support. The end plates 1 and 2 are connected together by a stirrup i upon which is supported a motor 5 of a conventional form, said motor being driven from a suitable source of electrical energy 6 (see Fig. 3), connecting with the brushes 7 of the motor by wires 8 and 9; the electrical circuit being controlled by a suitable switch 10. The armature shaft of the motor 5 is provided with a worm 11, meshing with worm wheel 12 mounted upon a shaft 14, journaled in brackets 15 carried by the motor 5. The shaft 1 1 extends through the end plate 2 and is provided with a sprocket wheel 16, the object of which will presently appear.

Journaled in the end plates 1 and 2 is a shaft 17, and vertically alined with said shaft arc stub shafts 18, these stub shafts being carried by the lower part of the end plates 1 and 2, while the shaft 17 is journaled in the upper ends of said plates. Upon the shaft 17 are mounted hexagonshaped heads 19, and upon the stub shafts 18 are journaled hexagon-shaped heads 20, constituting part of an intermittently moving display rack for signs. The heads 19 and 20 at the angle points thereof are provided with notches 21 for engaging longitudinally disposed connecting rods 22 employed for pivotally connecting the links 23 of two endless chains together. The chains are located in close proximity to the end plates 1 and 2 and soldered or otherwise secured to said links are sign holding frames 24:, said frames being disposed longitudinally of the device and provided with open ends 25, whereby the signs or cards can be easily placed in said frames. In order that easy access can be had to said frames to change or re-arrange the signs at any desired time, we cut away the end plate 1 at its front edge, as at 26.

The end plate 2 is provided with revoluble idle sprocket wheels 27 for carrying a sprocket chain 28 in close proximity to the reduced end 29 of the shaft 17. The sprocket chain 28 passes over the sprocket wheel 16 of the shaft 14 and as will be presently described, imparts an intermittent movement to the endless chains carrying the sign holding frames 24.

Upon the reduced end 29 of the shaft 17 is loosely mounted a trip comprising a plate 30 having a flanged edge 31, a slot 32 and an arm 33. The arm 33 extends through a segment-shaped slot 34 formed in the end plate 2 (see Fig. 4 of the drawings, wherein the heads 19 are shown in dotted lines to more clearly show the construction upon the inner side of the end plate 2.) The arm 33 is connected to a bar 35, upon the inner side of the end plate 2, said bar being connected to an insulated contact arm 36, pivotally connected as at 37, upon the inner side of the end plate 2. The insulated arm 36 carries contact points 38 which are normally held in engagement with contacts 39 by a coil spring 40, this spring being connected to one end of the stirrup 4. The contacts 39 are carried by a piece of insulation 41 secured to the end plate 2, and these contacts together with the contact points 39 control the illumination of the signs carried by the movable frames 24.

Loosely mounted upon the reduced end 29 of the shaft 17 is a ratchet mechzmism embodying a yoke having depending arms 42, a pierced lug 43 for receiving the end 29 of the shaft 17, and a radially disposed arm 44 for a pivoted weighted pawl 45. One of the arms 42 is provided with a pin 46 for engaging in the slot 32 of the trip plate 30, while the opposite arm is provided with a depending flanged projection 47, the object of which will presently appear.

The reduced end 29 of the shaft 17 is provided with a square shank portion 48, for a ratchet wheel 49, said wheel being retained thereon by a nut 5 screwed upon the threaded portion 51 of the shaft 17. The ratchet wheel 49 is normally engaged by the weighted pivoted pawl 45 carried by the ratchet yoke. The flanged edge 31 of the trip plate 30 and the flanged projection 47 of the yoke arm 42 extend downwardly upon the sides of the sprocket chain and are adapted to be engaged by the pins 52, which make a sliding contact, first elevating the plate 30 and then elevating said plate and the yoke in unison.

Fitting over the end plates 1 and 2 and the mechanism just described is a detachable l l l l l l I l i l {I l I l l l l l hood 53 having its front wall provided with an opening covered by glass or similar transpzn'ent material. Through this opening signs carried by the frames are dis played.

The hood above the opening 54 is provided with a longitudinally disposed reflector 55, in which is located a plurality of incandescent lamps 56, said lamps being in circuit with a suitable source of electrical energy 56 (see Fig. 4) and with the contacts 39. Incandescent lamps can be of any approved form, and we do not care to con fine ourselves to the location of the source of electrical energy for these lamps or for the motor 5.

The operation of the mechanism just described, is as follows :-'When the motor 5 is placed in operation a rotary movement is imparted to the shaft 14, which in turn moves the endless sprocket chain 28. As this chain in ves the pins 52 are carried over a predescribed course and as they lie in the path of the projection 47, and the flanged edge 31 of the plate 30, the pins 52 will contact with these elements once during each circuit or circumvention of the sprocket chain 28. hen one of the pins 52 impinges the flanged edge 31 of the plate 30, said plate is moved upwardly and through the medium of the arm 33, bar 35 and the pivoted insulated arm 86, the electrical circuit through the incandescent lamps 50 is broken, (see dotted lines Fig. 4) extinguishing the lamps while the frames 24 are being shifted to display another sign through the opening 54. As the plate 30 is moved slightly in advance of the ratchet mechanism, the other pin 52 will engage the pro jection 47, elevate the ratchet yoke carrying the pivoted weighted pawl 45, and as this pawl normally engages the ratchet wheel 49, said wheel and the shaft 17 will be rotated a predetermined part of a revolution. The exact movement of the shaft 17 is governed by the number of teeth carried by the ratchet wheel 49 and by the stroke or movement of the ratchet yoke. The plate 30 and the ratchet yoke are gradually elevated by the pins 52 and when released by said pins, the yoke and plate assume their normal position by gravity, the weighted pawl 45 re ceding over the ratchet wheel 49 to obtain a fresh grip upon the same. The coil spring 40 immediately returns the bar 35 and insulated arm 36 to their normal position, again establishing a circuit to the incandescent lamps 56 and illuminating the sign carried by the frame 24, which has been moved in front of the sight opening 54.

As the endless chains carry a plurality of sign holding frames, numerous signs can be displayed by the device, the exposure of each sign being determined by the length of the sprocket chain 28 and the number of pins located upon said chain. It is desirable to actuate the ratchet mechanism at such intervals in order that each sign will be displayed a sufficient period of time to allow the said sign being read. The switch 10 for controlling the motor 5 and a switch 57 which we employ in connection with the lamps 56, are adapted to control the entire operation of the advertising dev ce, it of course being understood that the incandescent lamps 56 are only used when the device is operated at night and is located in dark places where the signs cannot be readily read.

It is obvious that the capacity of the device for displaying signs depends entirely upon the size of the device, and we desire it to be understood that such variations and modifications of the invention can be resorted to, as are Within the scope of the appended claims.

Having now described our inventlon what we claim as new, is
